It has often been observed that TN governments were undisciplined towards national policies. For their narrow political gains they don't mind toppling the Union governments.Let that be DMK or AIADMK.
It's been the mindset of people of TN with strong regional feelings and language barriers, which never let any national party to step in to state politics.This is a bad signal for the stability of National governance.
I think first the people have to change to bring these narrow party leaders to respect Indian constitution.
Not respecting SC judgement by a responsible entity such as state govt is height of disrespect. It has happened so in military ruled nations like pak during musraf rule, Hitler rule of Germany and now in Tamil nadu.
